The next sections detail how to install and configure the LFS system
scripts needed during the boot process. Most of these scripts will
work without modification, but a few require additional configuration
files because they deal with hardware-dependent information.

System-V style init scripts are employed in this book because they
are widely used and relatively simple. For additional options, a hint
detailing the BSD style init setup is available at http://www.linuxfromscratch.org/hints/downloads/files/bsd-init.txt.
Searching the LFS mailing lists for “depinit”, “upstart”, or “systemd” will also offer additional information.
